A Four-Port Bidirectional Dc-Dc Converter For Renewable Energy System And Microgrid, Xia Du Jan 2020

A Four-Port Bidirectional Dc-Dc Converter For Renewable Energy System And Microgrid, Xia Du

All Graduate Theses, Dissertations, and Other Capstone Projects

Renewable energy has nowadays become important in electrical power applications. Power converters play an important role in integrating these distributed energy sources. However, due to their intermittence characteristics, e.g., the output power provided by the PV and wind turbine is not stable, either an energy storage system will be used or microgrid is formed between the main grid and the sources. To integrate these renewable energy sources and manage the power flow, a multiport converter is preferred because it is highly beneficial and cost-efficiently than the traditional solution that using multiple individual power converter for each source. This thesis proposed …


Control Of A Grid-Tied Single-Phase Inverter For Renewable Energy Integration, Dianzhi Yu Jan 2020

Control Of A Grid-Tied Single-Phase Inverter For Renewable Energy Integration, Dianzhi Yu

All Graduate Theses, Dissertations, and Other Capstone Projects

With increasing demand for generating electricity from clean energy, renewable energy sources (RESs), such as wind and solar, has gained much attention due to the clean and quiet characteristics. In many applications, connecting multiple RESs of different types (e.g., wind and solar), voltages, and capacities to a power grid or load is required. Single- phase inverters have been widely installed in residential power system to meet the full or partial load demand. In this work, multiport converters were developed for integrating multiple RESs, wind turbine and photovoltaic (PV) panel. Since the intermittent characteristic of the RESs, an energy storage device, …


A Four-Port Dc-Dc Converter For A Hybrid Wind/Solar Energy System, Jiahong Ning Jan 2020

A Four-Port Dc-Dc Converter For A Hybrid Wind/Solar Energy System, Jiahong Ning

All Graduate Theses, Dissertations, and Other Capstone Projects

With the increasing demand for clean and hybrid energy in the last decades, more and more attentions are paid to the renewable energy, e.g., wind and solar energy. According to the International Energy Agency, solar power was growing-fastest source in the world. In a hybrid wind/solar system, power converters play an important role in in power management and the voltage regulation. Gradually, power systems have undergone a paradigm shift from centralized generation to distributed generation. Smart grid, which is a combination of power systems and communication networks, was proposed to allow power systems to fit the future system challenge. However, …
